Data sets

CRU TS4.01: Climatic Research Unit (CRU) Time-Series (TS) version 4.01 of high-resolution gridded data of month-by-month variation in climate (Jan. 1901-Dec. 2016) University of East Anglia Climatic Research Unit (CRU), I. C. Harris, and P. D. Jones 10/gcmcz3

Xibalbá: Underground Temperature Database F. J. Cuesta-Valero, H. Beltrami, A. García-García, J. F. González-Rourco, and E. García-Bustamante

Short summary
We provide new global estimates of changes in surface temperature, surface heat flux, and continental heat storage since preindustrial times from geothermal data. Our analysis includes new measurements and a more comprehensive description of uncertainties than previous studies. Results show higher continental heat storage than previously reported, with global land mean temperature changes of 1 K and subsurface heat gains of 12 ZJ during the last half of the 20th century.
